Hey all- I'm using QBFC to generate invoices in a Quickbooks integrating app. I'm getting an exception thrown for lineItem.Amount.SetValue(val as Double) when I try to enter a programmatically generated double. The following does not work: lineItem = invoice.ORInvoiceLineAddList.Append.InvoiceLineAdd Dim amount as Double amount = s...
I have the following bit of code, however when compiling it with GCC 4.4 with various optimization flags I get some unexpected results when its run. #include <iostream> int main() { const unsigned int cnt = 10; double lst[cnt] = { 0.0 }; const double v[4] = { 131.313, 737.373, 979.797, 731.137 }; for(unsigned int i = 0; i ...
I'm working on a cross-platform app for Windows and Mac OS X, and I have a problem with two standard C library functions: strtod() - string-to-double conversion sprintf() - when used for outputting double-precision floating point numbers) Their GCC and MSVC versions return different results, in some digits of mantissa. But it plays a...
I am storing a list of numbers (as Double) in a text file, then reading them out again. When I read them out of the text file however, the numbers are placed into the text box as 1.59993499 for example, instead of 1.6. AssignFile(Pipe, 'EconomicData.data'); Reset(Pipe); For i := 1 to 15 Do ReadLn(Pipe, SavedValue[i]); Close...
I tried following code snippet and output is surprising me: #include <stdio.h> #include <math.h> int main() { double num; unsigned char ch; ch = 19; num = 1.0E+20 ; num += ch * 1.0E+18; printf("E18 = %lf \n",num); printf("E18 = %e \n",num); ...
Hey, I need to be able to convert from a Delphi Real48 to C# double. I've got the bytes I need to convert but am looking for an elegant solution. to the problem. Anybody out there had to do this before? I'm needing to do the conversion in C# Thanks in advance ...

The problem. Microsoft Visual C++ 2005 compiler, 32bit windows xp sp3, amd 64 x2 cpu. Code: double a = 3015.0; double b = 0.00025298219406977296; //*((unsigned __int64*)(&a)) == 0x40a78e0000000000 //*((unsigned __int64*)(&b)) == 0x3f30945640000000 double f = a/b;//3015/0.00025298219406977296; the result of calculation (i.e. "f"...
I'm writing a framework for writing HDF files with JAVA (Using some existing framework). I need to keep compatibility with octave. That is, octave should be able to read the files my framework writes and vice versa. My question is, does Octave have two data types - float and double or it uses only double? thanks ...
Hi, I've found the following question Convert Delphi Real48 to C# double but I want to go the other way, C# to Delphi. Does anyone know how this can be done? I've tried reverse engineering the code but without much luck. Update: I'm after C# code that will take a double and convert it into a Real48 (byte[] of size 6). Thanks ...
I have a file called "physics 1b.sh". In bash, if i try x="physics 1b" grep "string" "$x".sh grep complains: grep: physics 1b: No such file or directory. However, when I do grep "string" physics\ 1b.sh It works fine. So I guess the problem is something to do with the variable not being expanded to include the backslash that gr...
Hi, I'm printing a variable say z1 which is a 1-D array containing floating point numbers to a text file so that I can import into Matlab or GNUPlot for plotting. I've heard that binary files (.dat) are smaller than .txt files. The definition that I currently use for printing to a .txt file is: void create_out_file(const char *file_nam...
Double has range more than a 64-bit integer, but its precision is less dues to its representation (since double is 64-bit as well, it can't fit more actual values). So, when representing larger integers, you start to lose precision in the integer part. #include <boost/cstdint.hpp> #include <limits> template<typename T, typename TFloat>...
Actually I'm working with BufferedImages, that provide me pixel values in int type. Do you know a Java object to represent an image that the pixel value in double or float type? ...
Hi I an issue with editors in a JTable. I have a column which displays data as 26,687,489,800.00 ie: Double. When the user clicks the cell to edit the data it is displayed as -2.66874908E10. I want the data to be edited as it appears when it is displayed ie: 26,687,489,800.00 - without the E10 etc... Any help would be appreciated. M...
Context: .Net, C# I want to print a complex number made from two doubles. The sign needs to show on the imaginary part. I'd like to use the default double formatting for each part to minimize the number of characters. I tried using String.Format("{0:+G;-G}{1:+G;-G}j", real, imaginary) but this ended up printing: "+G-Gj". Not quit...
In Visual C++ i wrote the following sample in a C++ program: float f1 = 42.48f; double d1 = 42.48; double d2 = f1; I compiled the program with Visual Studio 2005.
